How to use these
Each calculator works offline. Your inputs never leave your browser, never get saved, never feed an email list. Each runs in about 30 seconds and returns a clear answer with a breakdown of the math.
At the end of each calculator, if your result suggests you might benefit from one of the ProbatePack packs, you will see a recommendation for the specific tier that fits your situation. If your result is straightforward enough that you do not need a pack, the calculator will say so.
These calculators are preparation tools using Irish tax and probate rules for 2026. They are not legal or tax advice. For estates that are complex, contested, or above €1.5 million, consult a solicitor.
